Ovitrap Monitoring of Aedes aegypti and Aedes albopictus in Two Selected Sites in Quezon City, Philippines

In recent years, Aedes mosquitoes have become a serious health threat in the Philippines, causing a dramatic increase in dengue incidence. To design and implement adapted vector control measures, knowledge of vector composition and abundance is essential. Surveillance of mosquito populations using ovitraps was conducted for about two years (from April 2018–February 2020) in two selected sites (Sitio Payong and Villa Beatriz in Old Balara, Quezon City). These areas were identified as potential sites for small-scale pilot trials of the sterile insect technique. Aedes aegypti and Ae. albopictus were present in both sites, but Ae. aegypti was about 20 times more abundant than Ae. albopictus. There was a significant difference between the two sites in the number of eggs collected weekly but not in the OI. The number of Aedes spp. eggs collected were found to positively correlate with the maximum daily temperature. These data provide comprehensive, evidence-based information that will help in the design and implementation of Aedes control measures, as part of wider public health interventions for prevention and control.
